I have had the ninja twisti for about 2 weeks now, and it is P-E-R-F-E-C-T for smoothies, it is a great size, i am always making to much and with the glad it comes with, it is always the right amount and no thinking of how much to add or what if i added to much, there is like a max on the glass for the liquid amount to add, which i need this, and use it all of the time. the timer is great do not have to worry about it, the smoothie is always silky smooth every time. There is no chunks of ice when i use that in my smoothie left over, it is small and very light, i keep it on the counter because i use it 2 or more times a day.
